Author 'Gilbair' (Id 231097 ) : This photo not retouched but only cropped is the reflection on the ripples, the edge of a dock.
The dock was very very photogenic which is why I took it out of the frame. The alternating lines of white, beige and grey correspond to... The metallic trim of the dock. Not much to see with the photo.
